Alphabet's Waymo announced it has significantly expanded its autonomous ride-hailing service in Austin, growing its coverage from 37 to 90 square miles and adding new neighborhoods and destinations to its network.

Alphabet's Waymo is expanding its service in Austin, Texas, to 90 square miles from 37 square miles earlier, the software giant's self-driving unit said on Thursday, seeking to protect its top position in the city from rivals such as Tesla.

“With recent growth in Austin and California, plus opening in Atlanta with Uber, Waymo now serves more than 700 sq mi across the US,” the company said. According to Waymo, it has driven over 100 million fully autonomous miles without a human behind the wheel.
